Tau vehicle defenses

[exeteroborach]

Hey all.
Seems to me that with the current edition GW has taken away any and all defensive upgrades/ strats for the 3 Tau tanks? I haven't played them since 5th but they used to get Disruption Pods, Flechette Launchers and such for protection. Now it doesn't look like they get anything? Am I just missing them? I know the Hammerhead has gotten some serious damage output but given the Tau's technology it should still be able to use a strat for some defensive buffs. My first born tanks/ Dreadnoughts still get to use their smoke launchers.
Thanks.

Can the vehicles take shield drones? If so, that's a strong defense.

I think there's a strat that allows a drone in another unit to intercept wounds so that could be used to help vehicles.
